Filter List within visual

Hi everyone.

I try to develop a supplier management tool for my master thesis and I'm pretty much a beginner in Power BI.

The idea is to select risk countries (e.g. right now Ukrain or China due to Covid Lockdowns) (top left) to see the risk suppliers in these selected countries (Left bottom). As a result there should be shown the alternative suppliers for the "Group of Material" (here: screws) (bottom right).

In the screenshot you see on the right bottom all (including the one from risk country) suppliers for screws. 

Key Question:

How could i filter the one supplier from the risk country (left bottom) from the right bottom list?

The Lists have the same dimensions.
